The per-gallon prices of diesel fuel and gasoline each posted increases of around ten cents last week, the Energy Department reported Monday.

Diesel fuel rose 9.6 cents to a national average $2.801 a gallon, its third-straight weekly gain and its highest price in almost a year.

The increase followed last week’s 10.5-cent spike, but still left the price of a gallon of diesel 48.7 cents below year-ago levels, DOE said.

Prior to this three-week upturn, diesel prices had declined for five straight weeks, falling a total of 9.2 cents during that span.

Gas increased by exactly ten cents to $2.674, its highest national average price since June 22, when the per-gallon price hit $2.691, DOE said.

The gains have been propelled by rising crude oil prices, which closed over $80 a barrel last week for the first time in a year. Oil was trading at about $67 a barrel at the end of September.

Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
